I To 7] fltlm/i if may mildern understood, the apparatus may be used for yze Be it. lniowiitliat I, CARL Hassnam'a subject ot' the King of Wur'ttemberg, residing at Aalen, Germany, haveinvented an Improvement in Atoinizers, of which the following` isa specification. j y' f M present invention relates to anatomif/.er particularly adapted yfor liquids vsuch as oils'aiul like materials when the apparatus` isus'ed as a` carbureter, but as will be atoiiiizing aiiy substance in aliquid form. The objects of my present invention are to provide an atomizer in which the flow of the liquid to. be atomized and4 consequently the supply of thesame, is-regulated and controlled bipr theair supplied to the apparatus andI by wil ich" the liquid is atomized, and

' also to subdivide the yair currents so that the mixture of the air and liquid ,will be as coinplete as possible. Y

wlien in other positions, when the area ofthe air inlet is-gi'eater. than .the area ofthe mixs ing chaiiihcr orifice, there will be an accu? mulation of air in the mixing chamber under .gi-eater or less pressure, which will act to i'etard the How oit .the liquid and hence control the same hy regulating the air pressure in the niixiiigehamher. :I also preferahlyemploy partition walls forminga chamber into whicl a mixture of air and liquid is discharged soy that the liquid is further mixed lwith -additional quantities of .air to insure. a

thorough mixing of the same.
